Title: Improvements in stapling mechanism for use in printing machines
IPC: B27F7/23
Filed: 1932-01-23
Abstract: 395,762. Stapling. HOW & CO., Ltd., R., QUICK, C. G., and WHITEHEAD, W. A., 109, Borough Road, London. Jan. 23, 1932, No. 2139. Addition to 320,137, [Class 89 (iii), Nailing &c.]. [Class 89 (iii).] Relates to rotary stapling mechanisms for printing machines wherein the stapling units are relatively adjustable longitudinally for varying the pitch of the staples, and consists in forming the stapling cylinder in a plurality of relatively-adjustable parts, each part having a staple plunger and associated mechanism, and in providing correspondinglyadjustable shaping horns. The main shaft 1, which.is driven by a gear wheel 12, carries a cylinder 5 for stapling units 6 and an operating cam 7 therefor, and is keyed to a sleeve 22 which carries a stapling cylinder 25 and associated cam 27. The cam 7 is driven by a pinion 9 on a shaft 10 driven from the gear wheel 12 by a pinion 11. The cam 27 is driven by a pinion 29 keyed to the shaft 10. The shaft 10 is supported in bearings carried by a frame 4, which frame also carries bearings for the main shaft 1. An extension 17 at the left-hand end of the frame 4 supports a stretcher 19, to which is fixed a horn 20 co-operating with the stapling cylinder 5. The sleeve shaft 22 is mounted in bearings carried by a second frame 24 which can slide on the frame 4. The frame 24 carries also a bearing for the pinion 29 and a horn 33 co-operating with the cylinder 25. To vary the pitch of the staples, the frame 24 is caused to slide on the frame 4 by turning an adjusting screw 39. Also, by means of an adjusting screw 36, the frames 4 and 24 can be caused to move bodily to the left or right. as a unit to vary the distance of the staples from one edge of the product. The cams 7, 27 may be of the kind allowing staples to be inserted at each or at alternate revolutions of the cylinders. In order to vary the wire feed correspondingly, the wire feed mechanisms are driven from the pinion 9 or from a second pinion 16 on the shaft 10, pinions 45, 46 on a wire-feed drive-shaft 47 being selectively engageable with the pinion 9 or 16 by,means of a hand-wheel 54. A latch 55 locks the shaft 47 in either driving position or in an idle position. 'Where a helically toothed driving gear 12 is employed, the gear 12 can be disconnected from the shaft 1 during longitudinal adjustment of the frame 4. At such time, the shaft 1 is locked against rotation by means of a straighttoothed gear wheel 58. Thrust bearings 59 and wedge devices 60 at each end of the shaft 1, 22 provide for axial adjustment of the stapling cylinders for lining up with the horns. The dies in the co-operating clenching cylinder are adjustable to allow for adjustments of the. stapling cylinders.

Title: Improvements in pressure responsive electric switches
IPC: H01H35/32
Filed: 1949-01-28
Abstract: 663,381. Distortable-container switches; pressure actuation of switches. BENDIX AVIATION CORPORATION. Jan. 28, 1949. [May 25, 1948] No. 2448/49. Class 38 (v). [Also in Groups XIX and XXXIII] A pressure responsive switch, primarily intended for use in conjunction with an electrically controlled parachute release (see Group XXXIII) has separate adjusting devices for altitude and ground barometric pressure. The switch comprises inner and outer bellows 48, 46 defining a hermetically sealed enclosure containing the switch contacts 65, 66. The upper ends of the bellows are sealed to a plate 44 attached to a fixed plate 40, whilst the lower end of the bellows 46 is sealed to a plate 67 carrying the contact 66 and movable against the bias of a spring 49 to close the contacts 65, 66 as the pressure outside the bellows increases. The lower end of the bellows 48 is secured to an axially adjustable tubular contact carrying member 56 which passes freely through a screwed hub 53 attached to an altitude adjusting gear wheel 54. A nut 58 screwed onto the member 56 is biassed into abutting engagement with the gear wheel 54 by a spring 51 acting between the member 56 and a fixed sleeve 52, so that when the gear 54 is turned, the rotation of the screwed hub 53 in the screwed sleeve 52 causes an axial movement of the gear wheel 54, nut 58 and contact carrying member 56 to determine the altitude setting. To compensate for ground barometric pressure a gear wheel 57 is secured to the nut 58 so that by turning the gear wheel 57 the contact carrying member 56 may be adjusted axially relatively to the altitude setting gear wheel 54. The gear wheels 54, 57 are turned by means of worms 76, 77, the worm 77 being at an angle to worm 76 to enable the use of teeth on the gear wheel 57 parallel to the axial movement of the altitude gear 54 so as to avoid reaction between the two setting mechanisms. The worms 76, 77 are turned by adjusting members 26 with knobs 30, 38 which have to be initially pushed in against springs 32 to engage pin and slot connections 37, 78. When the knobs are released, flexible washers 28 provide pressure tight seals for the switch casing 12 which is connected at 20 to a suitable pressure point. As the altitude and ground barometric pressure setting scales 55, 59 move with the gears 54, 57 to which they are attached, the index plate 75 is resilient and bears against the scales so that it follows their axial movement and avoids parallax error. The contact 65 Fig. 5 is fixed to a glass insulated central conductor within an insulating eyelet 72 and connected to a metallic tube 73 surrounded by an insulating sleeve 74 within the member 56, a lead 68 being sweated to the tube 73.

Abstract: 763,816. Pneumatic tyres. UNITED STATES RUBBER CO. Jan. 28, 1955 [March 10, 1954], No. 2616/55. Class 144 (2). To eliminate or reduce tyre squeal and slap, a pneumatic tyre tread T is formed with a crown radius H of at least 145 per cent of the tyre section G and comprises at least five circumferential, functionally continuous ribs 13- 19 separated by circumferential straight, zigzag, or sinuous grooves 10, the tread rubber decreasing in thickness from the shoulders to the tread centre line, the outermost ribs 13, 19 each having a mean width less than that of each of the ribs 14, 18 next adjacent thereto and the remaining ribs 15, 16, 17 each having a mean width greater than that of each of the ribs 14, 18. As shown, the tread comprises seven ribs, with the centre rib 16 formed wider than the adjacent central ribs 15, 17. With this arrangement the widths of the ribs are dimensioned so that the cross-sectional areas of the tread portions defined by the tread surface, the carcase periphery or rubber line L, and the radial lines R-1, R-2 from the crown centre through the laterally outer edges of ribs 13, 19, and the centre of the grooves 10 respectively are substantially equal. Such an arrangement may be applied to a tread having any number of ribs from five upwards.
Patent GB-810490-A (GB)
Title: Processes for sweetening hydrocarbon oils
IPC: B01F27/91
Filed: 1956-01-26
Abstract: Mercaptans are removed from hydrocarbon oils by intimately contacting, in the presence of a free oxygen-containing gas, with an aqueous alkali metal hydroxide solution in and by means of a propeller mixer, the volume ratio of aqueous alkali metal hydroxide to mercaptan-containing hydrocarbon oil supplied to the propeller mixer being less than 0.5:1.  Aqueous sodium and potassium hydroxide solutions may be used, to which solutizers for mercaptans and for oxygen may be added.  Solutizers for mercaptans referred to are amino- and hydroxy-alkyl amines where the alkyl groups contain 2 to 3 carbon <PICT:0810490/III/1> atoms, glycols, amino-glycols and diaminoalcohols containing 3-5 carbon atoms, diamino-, dihydroxy- or aminohydroxy-dialkyl ethers or thioethers where the alkyl groups have 2-3 carbon atoms, alkali salts such as potassium salts of fatty acids containing 3-5 carbon atoms, e.g. isobutyric acid, or of hydroxy- or amino-fatty acids containing 4-7 carbon atoms, or of phenyl acetic acid or hydroxy- or aminophenyl acetic acids, and alkyl phenolates such as cresolates.  Solutizers for oxygen specified are phenolates, which may be substituted by alkyl groups with a total of not more than 3 carbon atoms.  An oxidation catalyst for mercaptans, such as tannin, may be used.  An excess of 50-200 per cent with respect to the theoretical amount of oxygen required for oxidation of the mercaptans is preferred; 10-40 per cent of a peroxide, based on the stoichiometric quantity of oxygen, may also be added.  The process may be carried out at 0-80 DEG  C. and at normal or elevated pressure, and may be effected continuously. From 0.2-0.4 parts by volume of alkali to 1 part of oil may be used.  The oils may be pretreated with dilute aqueous alkali metal hydroxide solution to remove hydrogen sulphide and part of the aromatic mercaptans, and also with a similar solution containing a solutizer for mercaptans to remove most of the mercaptans. Hydrocarbon oils treated may be those boiling not higher than 350 DEG  C., such as straight run or cracked gasolines and kerosines, e.g. catalytically cracked gasolines, and reformed gasolines; when the oils contain unsaturated components, an antioxidant may be added, e.g. an arylamine or alkyl phenol.  In the Figure, 1 designates a propeller mixer comprising a rotating vane 3 mounted on a shaft 2 and surrounded by a jacket 4, in which the mixture of oil and alkali is introduced via inlet 5.  The mixture is sucked down by the vane and enters the zone between the jacket and the outer wall via the bottom of jacket 4.  The mixture leaves the apparatus at outlet 6.  The inner wall of the apparatus may be provided with baffles 7.  The vanes may revolve at 250-2500 revolutions per minute.  The mixture of oil and alkali is passed to a settling tank to separate the phases, and the aqueous alkali recycled.  The process is compared with a similar process using a turbomixer instead of a propeller mixer.  Specifications 499,678, 503,644, 509,669 and 712,056 are referred to.
